Yes very nice container indeed, and if you ever sell it due to size constraints I would buy it
If your top off is just fresh water only and no additives how about setting up a 40gl tall freshwater tank near by and add some neon tetras lol that way you would have two nice tanks for your other half to view lol
Lots of folks use a 55gl drum and with a pump and some long tubing run it from a garage or closet near bye instead of having a massive drum of water as an end table.
